extend by operating to 1 °F (– 17.22 °C) lower than the set

is installed, it will cycle ON and OFF to maintain the set
point while the compressor stays on longer to dehumidify.

5.4.3 Exiting programming mode
This section gives information on how to exit programming mode.
To exit the programming menu manually, simultaneously tap and hold the-
Up (+) and Mode icons for three seconds until the room temperature is displayed.
Alternatively, the display automatically exits the programming menu aer 10 sec-
onds of inactivity.
The control's software version (such as "40") appears in the display for one second-
prior to the manual or automatic exit from the programming mode. The control en-
ters OFF mode after exit.
5.4.4 Identifying programming fault codes
Fig.  on page 3
To protect the unit, certain fault conditions trigger a lockout that shuts down the control.
The control will not restart until the fault is repaired. The type of lockout associated with
the fault depends on the type of fault detected (refer to the Fault and Status Codes table
below) in combination with the level of protection (refer to the Fail Safe Levels table be-
low) that was programmed in the P-5 parameter (refer
Fault and status codes
Code Description
HPF High Pressure Switch Fault: indicates high
refrigerant pressure. This fault is not applic-
able in HEAT mode.
LPF Low Pressure Switch Fault: indicates
low refrigerant pressure. This fault has a
three minute shutdown delay (for display
firmware #41 and newer).
PLF Low Pump Flow Fault: indicates high-water
temperature in the condensing coil or low
pump flow.
IL/- - Indicates a loop water sensor failure.
IS/- - Inside Sensor: indicates the display built-in
temperature sensor is damaged.
Ar/FL Indicates the air filter replacement timer has
expired.
